A) What is confirmation bias? Confirmation bias, literally the preference for confirmation. A broader description is that confirmation bias is a way of thinking or behaving by which people have a tendency to confirm their own opinion or thought. Furthermore, people will only seek or accept arguments or facts that confirm their opinion or thought. Furthermore, people will not notice or rather devalue arguments that contradict their opinion or thought. So confirmation bias is the tendency to be selective about the information that will be used or believed, or in other words; look at the world through a filter. Say no to plagiarism.

Only recently have news stories portrayed them as the culprits of global warming and major producers of harmful gases. In all the newspapers and in all the programs it is said that it is the farmers' cows or pigs, and above all intensive farming, that produce these harmful gases. But if you look at the farmers' interest groups, I know it's also a bit biased, you see that they do everything they can to produce less and less harmful gases every year. Only in the news there is no time or place for farmers' interest group, so the normal civilian will blame the farmer. That's why they are asking the government for additional regulations, which harm farmers and which, in the long term, will fail to prevent global warming. In case the government adopts such regulations, there would be no farmers left in the Netherlands, so we will have to import meat, milk and other products, which would have to be imported by truck or even plane. But no one even thinks about these harmful emissions because people always need their cars, trucks and planes. This confirmation bias, provided by the news, will lead to irrational decisions by the government, setting rules for farmers that will cost them their farms. Furthermore, the problem would simply solve the problem, without solving it. C) Karl Popper's criterion provides a reasonable requirement for scientific theories. According to Popper, you can call a scientific theory a theory only if and only if you can prove your theory wrong by observations. A scientific theory is the fallibility that makes it a good theory and not the fact that it is a foregone conclusion. By looking for counterarguments or observations, the scientist will be protected from his own confirmation bias, since he must look for something that contradicts his theory. So they don't just look for experiments that confirm their theory. And when the scientist or any specialist cannot find anything that contradicts his theory, it should be true, but that does not mean that one can stop looking for counterarguments or observations. This continuous search for observations that prove their theorem is wrong will make it a reliable theorem and prevent them from confirmation bias.
